Study Objectives: The aim of this study was to adapt the internationally accepted Performance Enhancement Attitude Scale to the Turkish culture and determine the reliability and validity of the adapted version. Methods: A total of 207 Turkish individuals, 110 males (mean age=39.33 +/- 2.45 years) and 97 females (mean age=38.91 +/- 1.51 years), aged 18 and over, who regularly engaged in exercise, participated in the study. In the analysis of the data, the exploratory factor analysis was used to determine the underlying structure of the scale items, and the confirmatory factor analysis was performed to test the compatibility between the model and the data. In addition, the Cronbach alpha reliability analysis was undertaken for reliability, and the Pearson product-moment correlation and test-retest values were obtained to examine for the item correlation analysis. Results: The cross-sectional multi-sample Performance Enhancement Attitude Scale consisted of 17 independent items under a single sub-dimension as in the original version. In our study, the internal consistency coefficient of the Turkish version was calculated as 0.88, the factor loads varied between 0.40 and 0.67, and the test-retest correlation was 0.79. Conclusions: These findings showed that the Turkish adaptation of the Performance Enhancement Attitude Scale can be reliably used for research purposes. It may be thought that is important to bring an internationally accepted instrument to the Turkish literature to be used in future research in order to investigate the performance-enhancing attitudes of exercise.
The Performance Enhancement Attitude Scale in Team Sports; Validity and Reliability Study
(Mattioli 1885, 2022) Uysal, Yucel; Toros, Turhan; Cetin, Mehmet Cagri; Ozyol, Funda Coskun; Serin, Emre; Guzel, Sinan; Ozturk, Rabia Yildiz
Study Objectives: The aim of this study was to evaluate performance enhancement attitudes of active licensed athletes in team sports. Methods: The research sample of this study consists of 371 actively licensed athletes aged 18 and over in team sports (football, basketball, volleyball, and handball). The average age of the athletes is 24.42 +/- 2.12. Participation in the study was carried out on a voluntary and confidential basis. Performance Enhancement Attitude Scale, developed by Petroczi (2002) and adapted to Turkish by Yildiz & Toros (2018), was used as a data collection tool. Results: In the analysis of the data, the Cronbach alpha coefficient test and the Pearson Correlation Coefficient were used to reveal the test-retest value. The Cronbach alpha coefficient for the team athletes of the scale was 0.84, and the test-retest reliability coefficient was 0.88. Conclusion: According to the research findings, the results of the reliability analysis reveal that the scale can be used on licensed athletes in team sports.
